This paper recommends an iterative approach to implementing IWRM that allows for adaptation and is tailored to solve specific water problems in Nigeria.There are cultural and educational barriers that hinder the adoption of technologies in educational practice. This is mainly owed to how the majority of teachers are still digital immigrants lacking adequate preparation to work in an environment of fast-paced innovation and without the corresponding updates of cognitive technology. In order to mitigate this problem, in this paper we present an alternative framework that intends to increase the effectiveness of technological application in broader educational contexts bringing together three constructs causally relating the domains of Cognitive and Motivational Competencies (CMC) - relating to people; Organisational Institutional Complexity (OIC) - educational systems and Behavioural Intentional Use of Technology (BIUT) relating to adoption of attitudes. Measurement indicators were applied to evaluate each construct in order to better predict teaching behaviour in a broader educational context. The framework evaluation was performed by two focus groups composed of experienced, highly specialised education consultants who assessed the pedagogical, technological, teacher's behaviour and overall institutional/organisational environment involving the proposed alternative solutions. The discussions and results show that participants agreed on the proposed framework's usefulness and its contributions to help teachers mediate the gaps between school and the outside world, all the while considering political and administrative barriers. The evaluators also highlight the structured motivational and self-efficacy aspects that must involve teachers and other stakeholders concerned with adopting a new social action profile for the benefit of collectives. The next work to follow this paper will be a dissemination proposal concerning the Brazilian National Educational Plan, a technological adoption that effectively meets Education's institutional principles in this country.Chrysanthemum is one of the most consumed and most valuable cut flowers worldwide. In this study, the effectiveness of three concentrations of either thyme oil (300,400 and 500 mg/l) or clove oil (150,250 and 500 mg/l) as additives in holding the postharvest solutions of chrysanthemum ''Arctic Queen White'' cut flowers were investigated. The experiments were carried out as a completely randomized design in three replicates. Many postharvest characteristics have been evaluated, such as the vase life of cut flowers, diameters of head flowers and stem, dry matter of flowers, total vase water uptake, total loss of water, relative fresh weight. Additionally, the chlorophyll contents, total sugar, and bacterial counts were determined. The results showed that the longest vase life of cut chrysanthemum was 36.50, 33.40 days, and 35.88, 31.33 days by addition of either the thyme oil (500 mg/l) or clove oil (250 mg/l) in holding solution as compared with distilled water (18.09 and 17.22 days) in both seasons. https://www.selleckchem.com/products/PCI-24781.html The highehemicals would be of great economic and environmental impact (Values).Wounds are major problems of developing countries that can be managed alternatively using traditional medicinal plants. Since majority of currently available drugs for wound management are expensive and pose problems such as allergy and drug resistance, it is pivotal for the world to have intensified inquiries on the claimed medicinal plants to come up with wound healing chemicals being affordable, effective and safe. Ethiopian traditional healers recruit a wide range of medicinal plants with wound healing activities. Root bark juice of , the leaves of and are claimed among others in the folklore medicine. Therefore, the aim of this study was to evaluate the in vivo wound healing activities of the root bark juice of , the leaves of and in mice.
The root bark juice of , the leaves of and were collected, dried, ground to coarse powders. Then the crude extract was obtained by macerating with 80% methanol. The filtrate was dried, reconstituted in appropriate solvent and the wound healiwas attained by 5% &amp;10% leaves of Dodonea angustifolia (P &lt; 0.01), 10% leaves &amp; root barks (P &lt; 0.05). Ten percent of &amp; (P &lt; 0.05) and both doses (5% &amp; 10%) of Dodonea angustifolia (P &lt; 0.01) significantly increased the tensile strength by 54.10%, 56.58%, 63.04%, and 79.19%, respectively against the control.
The 80% methanol crude extracts of the study plants support the traditional claims for healing of wounds as evidenced by an increase in wound contraction rate and tensile strength, decrease in Epithelialization period.

We describe how idealized functional models of early spatial, spatio-chromatic and spatio-temporal receptive fields can be derived in a principled way, based on a set of axioms that reflect structural properties of the environment in combination with assumptions about the internal structure of a vision system to guarantee consistent handling of image representations over multiple spatial and temporal scales. Interestingly, this theory leads to predictions about visual receptive field shapes with qualitatively very good similarities to biological receptive fields measured in the retina, the LGN and the primary visual cortex (V1) of mammals.Infectious diseases constitute a problem of great importance for animal and human health, as well as the increasing bacterial resistance to antibiotics. In this context, medicinal plants emerge as an effective alternative to replace the use antibiotics. The essential oil (EO) of Minthostachys verticillata (Griseb.) Epling (Lamiaceae) has demonstrated a strong antimicrobial activity. However, its instability and hydrophobicity under normal storage conditions are limitations to its use. Nanoemulsion technology is an excellent way to solubilize, microencapsulate, and protect this compound. This study aimed to obtain a nanoemulsion based on M. verticillata EO and evaluate its antibacterial activity against Staphylococcus aureus. The EO was obtained by steam distillation. Identification and quantification of their components were determined by GC-MS revealing that the dominated chemical group was oxygenated monoterpenes. Nanoemulsions (NE) were characterized by measuring pH, transmittance, separation percentage, release profile, and morphology.
